That's nice to see, but they're not the first manufacturer to do this; Acer has had a similar monitor with similar specs for at least 1 year, as have the other monitor manufacturers. In fact, I'm using the Acer right now, 21.2W max power draw. The Iyama is 20W max according to its specs. Probably the same LCD panel manufacturer (LG? Samsung?)
Hopefully monitors like this will be the norm, sooner rather than later.
